RE: [lwip-devel] Small fix for 'minimal'

[Vinay Purohit]

Christiaan,
I'm not familiar with the 'minimal' project. Do the memory leaks you
have mentioned also affect the 'regular' (for lack of a better term)
lwip stack?
Thanks

There is more than a small bug. There is a pbuf memory leak after about
1000+ small
echo's, and it seems larger files (>128 bytes (pbuf size)) aren't echo'd
properly.

Currently I'm rewriting the echo example, now using the true raw API
instead of the 'event API'.

Yep, found and fixed that a week ago in echo.c rev 1.4
